1 Calibration technology High-speed peumatic pressure controller Model CPC3000 WIKA data sheet CT Applications Industry (laboratory, workshop and production) Transmitter and pressure gauge manufacturers Calibration service companies and service industry Research and development laboratories Special features Pressure ranges bar Control speed < 3 sec. Control stability % FS Precision up to % IS (IntelliScale) Accuracy up to % IS (IntelliScale) Description Design With its compact design, its exceptionally reliable and patented control unit, and available measuring ranges of bar, the CPC3000 high-speed pneumatic pressure controller offers a wide range of application possibilities. The instrument is available as a desktop instrument or as a 19" rack-mounted unit. Application Since the controller offers an accuracy of up to % IS-50, and the pressure can be controlled extremely quickly, it is particularly suited as a production tool for gauge and/ or transmitter manufacturing or as a factory/working standard for the verification or calibration of all types of pressure measuring instrument. Functionality The large touch screen and the simple menu navigation guarantee maximum ease-of-use. In addition, its operability is further supported by the availability of a large number of menu languages. Depending on the application, the operator can choose between 3 input functions or menu blocks: 1) Numeric keypad for the precise input of the pressure value (setpoint) which will be controlled. High-speed pneumatic pressure controller model CPC3000 2) Step button block (max. 12). Each button thus represents a defined pressure value (these pressure steps are freely definable via the menu). 3) Jog buttons: with these, the 3 least significant decimal places of the current pressure value can be raised or lowered by a digit. Software In addition to the EasyCal professional calibration software, which enables the convenient calibration of pressure measuring instruments and the generation of test certificates, individual test programmes can also be created, e.g. within LabVIEW. For the serial command formats, the Mensor standard, SCPI or further optional instruction sets are available. Complete test and calibration systems The controller has an IEEE-488.2, an Ethernet and a USB interface, so that connection to existing systems is possible via one of these interfaces. If required, complete mobile or stationary test sets can also be assembled to customer specifications.

With gauge pressure sensors, the measuring range of the sensors must begin with -1 in order to carry out an absolute pressure emulation mbar abs % of measured value 38 and 2 freely programmable 1) % IS-50 accuracy: % of measured value in the upper half of the measuring range. 2) For a pressure type emulation, we recommend an native absolute pressure sensor, since the zero point drift can be eliminated through a zero point adjustment.

4 Easy operation via touch screen Standard desktop / main screen Shortly after power-up, the standard desktop (see following picture) displays. In this menu screen, one can switch between the operating modes using the buttons "MEASURE / CONTROL / VENT" (bottom left). entered setpoint Current pressure value Pressure unit (adjustable via pop-up menu) Operating mode Input menu field (Numeric/Step Funct./Jog Funct.) MEASURE In 'Measure' mode, the pressure present at the test port is measured with high accuracy (if you switch directly from "CONTROL" to "MEASURE" mode, the last controlled pressure in the connected test assembly will be maintained/locked). CONTROL In 'Control' mode, the instrument provides a highly accurate pressure to the test port, corresponding to the desired setpoint. VENT Immediately vents the system, including the test assembly connected to the test port, to atmosphere. Clear menu design (incl. expandable, helpful additional information) The menu screen is designed particularly clearly and offers the possibility of displaying additional information via the SETUP menu (see following picture). SETUP menu Current defined max. control range (configurable via SETUP) SETUP menu via the SETUP menu, the following items can be easily configured: Language (17 available in total) Maximum control range Step and Jog functions Communications settings Display of additional information Communication status of the interface* * displayed if required Display of the optional integrated barometer* Bargraph (% FS) as a visual indication of the current utilisation of the measuring range Page 4 of 7

5 Optimal setting options in 'Control' mode through 3 different input menu modes A) Direct setpoint input via numeric keypad Application: numeric setpoint input via Touchscreen. Operation The required pressure value/setpoint is entered using the numeric keypad and acknowledged by pressing the green 'tick' in the buttons underneath. This provides the setpoint adopted by the controller, which is immediately controlled and provided at the test port. Clear entry / clear last entry / Entry acknowledgment Screen with the input menu: NUMERIC B) Step-wise changing of the setpoint via defined steps using the Step function Application: simple calibration using defined test steps, without external software. Configurable via SETUP in % FS in the current pressure units Operation The fields in the Step menu contain defined setpoints (in % FS or actual pressure units), which are configurable via the SETUP menu. By pressing a step button, the corresponding pressure is immediately controlled and provided at the test port. Screen with the input menu: STEP C) Fine adjustment of the last 3 significant digits of the setpoint using the Jog function Application: Fine adjustment of a pressure value (up and down), e.g. to calibrate pressure gauges (bring the pointer to an exact point). Pressure increased by the Pressure reduced by the least significant digit x 100 least significant digit x 10 least significant digit least significant digit least significant digit x 10 least significant digit x 100 Operation The fields in the Jog menu contain defined values, which correspond to the last three significant digits of the current pressure value. Thus the current resolution of the pressure value directly affects the magnitude of these jog buttons. By pressing one of the jog buttons, the corresponding adjusted setpoint is immediately controlled and provided at the test port. Screen with the input menu: JOG Page 5 of 7
